Abstract
The utility model relates to a kind of automobile front longitudinal beam of continuous poor thick structure, comprises the firstth district, the secondth district, the 3rd district and the 4th district; Described firstth district, the secondth district, the 3rd district and the 4th section length are respectively 157mm, 271mm, 291mm and 131mm, and thickness is respectively 1.2mm, 2.95mm, 1.3mm, 1.22mm; The automobile front longitudinal beam of this continuous poor thick structure, the distribution of material of front side member is more reasonable, and not only the total energy-absorbing E of crash-worthiness critical for the evaluation and maximal impact have greatly improved, and quality decreases 3.6Kg relative to former front rail structure, achieves light-weight design; Save material, alleviated weight, reduce cost; Integral structure is simple, practical, is easy to promote the use of.
Description
Technical field
The utility model relates to automobile front longitudinal beam and manufactures applied technical field, especially a kind of automobile front longitudinal beam of continuous poor thick structure.
Background technology
Along with the improvement of road traffic condition, the continuous increase of automobile pollution and the raising gradually of the speed of a motor vehicle, traffic accident total amount and the personal casualty caused and property damage still sternness in recent years.Therefore the safety in operation of automobile receives publicity just day by day.How to improve the passive security performance of automobile in collision process, avoid to greatest extent or alleviate the important topic that the injures and deaths of member in auto against have become China's vehicle passive safety research.Conventional art increases to cost for improving vehicle collision resistant usually with complete vehicle quality.The automobile front longitudinal beam of prior art forms with the uniform steel plate punched of thickness, in order to weak part is not penetrated when ensureing to collide, have to use thicker plate to form, whole automobile front longitudinal beam steel plate thickness is increased, thus add the weight of car load, correspondingly increase energy consumption.
The optimization how realizing energy consumption uses, and then ensures that the minimizing of complete vehicle quality is the problem that people need to solve.
Prior art can not meet the productive life needs of people, for making up the deficiencies in the prior art, the utility model so design a kind of material thickness be continuous gradient distribution, intensity continually varying difference thick automobile front longitudinal beam, intensity can be realized change along with the change of sheet thickness, thus require for local strength the reasonable layout carrying out material, while reduction automobile front longitudinal beam quality, ensure that its crash survivability, achieve the double goal of lightweight and safety, avoid waste of material.
For realizing this technical purpose, scheme of the present utility model is: a kind of automobile front longitudinal beam of continuous poor thick structure, comprises the firstth district, the secondth district, the 3rd district and the 4th district; Described firstth district, the secondth district, the 3rd district and the 4th section length are respectively 157mm, 271mm, 291mm and 131mm, and thickness is respectively 1.2mm, 2.95mm, 1.3mm, 1.22mm.
As optimization technique scheme of the present utility model: the variation in thickness position in described firstth district, the secondth district, the 3rd district and the 4th district is provided with the transition region of 100mm length, and the material thickness of transition region linearly changes.
Compared with prior art, the beneficial effects of the utility model are: the automobile front longitudinal beam of this continuous poor thick structure, the distribution of material of front side member is more reasonable, not only the total energy-absorbing E of crash-worthiness critical for the evaluation and maximal impact have greatly improved, and quality decreases 3.6Kg relative to former front rail structure, achieves light-weight design; Save material, alleviated weight, reduce cost; Integral structure is simple, practical, is easy to promote the use of.
Utility model content
Accompanying drawing explanation
Fig. 1 is integral structure schematic diagram of the present utility model;
Fig. 2 is the continuous poor thick milled sheet structural representation of the utility model;
Wherein: 1, the firstth district, the 2, second district, the 3, the 3rd district, the 4, the 4th district.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Figure of description 1 ~ 2, in the utility model embodiment, a kind of automobile front longitudinal beam of continuous poor thick structure, comprises the first district 2 of district 1, second, the 3rd district 3 and the 4th district 4; Described first district 2 of district 1, second, the 3rd district 3 and the 4th district 4 length are respectively 157mm, 271mm, 291mm and 131mm, and thickness is respectively 1.2mm, 2.95mm, 1.3mm, 1.22mm.
As optimization technique scheme of the present utility model: the variation in thickness position in described first district 2 of district 1, second, the 3rd district 3 and the 4th district 4 is provided with the transition region of 100mm length, and the material thickness of transition region linearly changes.
The utility model is when making: whole front side member adopts continuous poor thick milled sheet bending ram to form, and ensure that between each section, material thickness is consecutive variations, and the position for variation in thickness is all provided with the long transition region of 100mm, the material thickness of transition region is line style change.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solutions of the utility model.
